使用spring整合Quartz实现—定时器(Maven项目做演示)
不基于特定的基类的方法
一,开发环境以及依赖的jar包
Spring 4.2.6.RELEASE
Maven 3.3.9
Jdk 1.7
Idea 15.04
二,不可少的jar依赖(添加在maven项目里面的pom.xml文件里面)
<dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>4.2.6.RELEASE</version> </dependency> <dependency> <groupId>org.quartz-scheduler</groupId> <artifactId>quartz</artifactId> <version>2.2.1</version> </dependency>
三,实现定时器时使用到的文件:
planWorkExcute.java --定时器执行的类
spring-plan.xml --配置定时器信息的xml
四,实现定时器步骤:
1,创建 planWorkExcute.java文件 ,在 cc.royao.plantask 包下。
package cc.royao.plantask; import java.text.SimpleDateFormat; import java.util.Date; import java.util.HashMap; import java.util.List; import java.util.Map; import java.util.concurrent.ExecutorService; import java.util.concurrent.Executors; import org.apache.log4j.Logger;//可以删除 import org.springframework.beans.factory.annotation.Autowired; public class PlanWorkExecute { Logger logger = Logger.getLogger(this.getClass());//logger打印日志,可以去掉 /** * 定时器执行的方法 */ public synchronized void withdrawNoAuditTask() { SimpleDateFormat outFormat = new SimpleDateFormat("yyyy年MM月dd日 HH:mm:ss"); System.out.println("开始提现免审核任务-------------------------------" + outFormat.format(new Date())); logger.info("开始提现免审核任务-------------------------------"); System.out.println("结束提现免审核任务-------------------------------" + outFormat.format(new Date())); logger.info("结束提现免审核任务-------------------------------"); } }
2,创建spring-plan.xml 配置文件 注:创建一个定时器的配置文件就行,如果需要多个定时器,直接在spring-plan.xml添加 bean和定义定时器类的方法就行,不需要创建多个xml,
· 关于那个定时器多久执行的 Cron表达式 可以参考://www.jb51.net/article/138900.htm

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd" default-lazy-init="false"> <bean id="job1" class="cc.royao.plantask.PlanWorkExecute" /><!-- 修改为你的定时类的路径 --> <!-- 可以创建多个定时bean --> <bean id="jobDetail_1" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean"> <property name="targetObject"> <ref bean="job1" /> </property> <property name="targetMethod"> <value>withdrawNoAuditTask</value><!-- 定时器类的方法名--> </property> </bean> <bean id="cronTrigger_1" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean"> <property name="jobDetail"> <ref bean="jobDetail_1" /> <!-- 这里对应上面bean--> </property> <property name="cronExpression"> <value>0/2 * * * * ?</value><!-- 0 10 0 * * ? 每天0:10执行 --> </property> </bean> <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean"> <property name="triggers"> <list> <ref local="cronTrigger_1" /> <!-- 每加一个定时器这里也要加--> </list> </property> </bean> </beans>
3,需要在 applicationContext.xml 中引入 spring-plan.xml 以下代码重点在最下
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
